One thing I did like was Ben Barnes as Prince Caspian. He's oddly attractive. I thought the kiss with him and Susan was a bit forced, though. Again, no connection to the characters for me.
Maybe I should watch this again. I feel like I'm being unfair somehow. I'll be sure to comment or update whenever I give it another go. So many people like this movie, so don't let my review keep you from at least renting it.
